Optimized Analysis on Coordination of High Speed Data Acquisition with Real-Time Processing in Power Quality Monitoring System and Its Application

In power quality monitoring system the coordination of high-speed data acquisition with real-time processing is always the key problem in actual system construction. On the basis of investigating the high-speed acquisition and real time processing modes in detail, the factors influencing the software implementation of high-speed data acquisition and real time processing are researched. In the construction of hardware and software for power quality monitoring system various coordination and optimization methods are synthetically explored, and taking the establishment of a real-time power network harmonic analysis system for example the application research is conducted. Practical engineering application results show that in aspects of sampling accuracy, high-order harmonic analysis, real-time data storage and anti-interference the optimized harmonic analysis system possesses better real-time performance. Thus the proposed method is available for reference in the design of real-time power quality analysis system.
